About Us

Pneucleus incorporates two core technologies into every Mass Flow Controller, the InSitu-Sense™ mass flow sensor, and the Tri-Planar™ proportional valve. These two technologies have been serving the analytical instrumentation market for more than 36 years. Pneucleus has combined these technologies to create a line of low-cost mass flow controllers specifically designed for applications in Analytical Instrumentation, Vacuum Coating, and other applications that require precise & reliable gas flow.

Founded by engineers in 1999, Pneucleus Technologies LLC specializes in serving engineers and are committed to delivering the highest value products in the industry. We all agree that “Value” is measured in performance, price, features, availability, customer service, flexibility, configurablility and more. Pneucleus encourages our customers to define what “Value” means to them and allow us to deliver it as defined.

Pneucleus has combined these technologies to create a line of low-cost mass flow controllers specifically designed for applications in Analytical Instrumentation, Vacuum Coating, and other applications that require precise & reliable gas flow. The key to our Low Cost product offerings is that they are designed to work exclusively with non-corrosive gases. This allows Pneucleus to eliminate the costly design features that are needed for handling the corrosive and otherwise dangerous gases found in semiconductor wafer processing. This significantly reduces the cost of manufacturing and insurance allowing us to pass the savings onto our customers.

The Pneucleus Advantage

Pneucleus Technologies’ MFC’s precisely control mass flow using its Tri-Planar™ proportional valve technology. The Advantage is that the Tri-Planar™ proportional valve incorporates a patented plunger design that compensates for parasitic thermal drift that may not be picked up by a PID loop. This valve has six possible orifice configurations and four power configurations allowing Pneucleus MFC’s to achieve outstanding flow stability and resolution while consuming minimal power and requiring minimal differential pressure.

Pneucleus Technologies mass flow controllers and mass flow meters measure mass flow directly through the use of its InSitu-Sense™ sensor technology. The InSitu-Sense™ sensor measures true mass flow by using proven MEMS technology involving thermal transfer as it relates to the specific heat characteristics of the gas being used. The “Advantage” is that the sensor is directly in contact with the flow stream which eliminates common-mode errors and provides superior repeatability, response-time and thermal stability. This technology is lower cost than standard by-pass designs and is used with non-corrosive gas applications only.

Pneucleus Technologies realizes that providing our OEM customers with the perfect gas measurement and control solution helps them keep the edge on their competition. Our engineers work directly with OEM engineers to design the perfect solution; whether it be as simple as extending thermal performance or more complex like achieving accuracies of 0.5% of reading. The Advantage is that we encourage our customers to request features and performance enchancements beyond the standard offering.
